Perinatal factors in the aetiology of hypopituitarism
12nd Department of Paediatrics, Semmelweis University, Budapest, Hungary.
Insights
Perinatal abnormalities like breech birth and asphyxia are linked to idiopathic growth hormone deficiency in children. Improved obstetrical care may reduce hypopituitarism incidence.
Area of Science:
- Pediatrics
- Endocrinology
- Obstetrics
Background:
- Idiopathic growth hormone deficiency (hypopituitarism) affects children, with potential links to perinatal events.
- Understanding etiological factors is crucial for prevention and early intervention.
Purpose of the Study:
- To investigate the association between perinatal abnormalities and idiopathic growth hormone deficiency in children.
- To explore the impact of obstetrical practices on the incidence of hypopituitarism.
Main Methods:
- Retrospective analysis of 73 children diagnosed with idiopathic growth hormone deficiency.
- Evaluation of perinatal factors including presentation and asphyxia.
- Thyroid-stimulating hormone (TSH) levels measured during thyrotropin-releasing hormone (TRH) tests to differentiate hypothalamic vs. pituitary damage.
Main Results:
- Breech presentation (32.9%) and asphyxia (15.0%) were more frequent in children with growth hormone deficiency.
- Increased C-section rates correlated with reduced breech births in hypopituitary patients.
- Breech delivery was associated with hypothalamic damage, while vertex presentation was linked to pituitary damage.
Conclusions:
- Perinatal abnormalities are significant etiological factors in childhood hypopituitarism.
- Improved obstetrical practices and perinatal care may decrease the occurrence of this condition.
Abstract:
The possible aetiological factors were studied in 73 children with idiopathic growth hormone deficiency. The following perinatal abnormalities were found to be more frequent than expected: breech presentation (32.9%) and asphyxia (15.0%). Parallel with an increased application of caesarean section there was a significant reduction in the incidence of breech birth among the hypopituitary patients. On the basis of TSH levels measured during TRH tests, most of the patients with breech delivery had a hypothalamic damage, while at vertex position the pituitary damage was more frequent. Of the two pairs of siblings with hypopituitarism both members of the first had breech birth and of the second high birth weight. It is concluded that perinatal abnormalities are important aetiological factors in hypopituitarism and that the occurrence of this disease can be reduced with improved obstetrical practice and perinatal care.
